▪ Abstract Fifteen years ago, we had a model of peroxisome biogenesis that involved growth and division of preexisting peroxisomes. Today, thanks to genetically tractable model organisms and Chinese hamster ovary cells, 23 PEX genes have been cloned that encode the machinery (“peroxins”) required to assemble the organelle.

Expose d'une nouvelle hypothese sur l'origine biochimique de la colchicine dans la plante. Il est suppose que l'acide trihydroxyphenylpyruvique agit commeprecurseur de cet alcaloide en subissant les transformations decrites par les formules (I) a (VI).

THE biogenetic origin of the tropane bases has recently been the subject of some discussion1,2, Mortimer1 suggesting that the tropane skeleton may be derived from the breakdown products of tryptophan metabolism. This novel idea is contrary to the accepted hypothesis that a base such as tropine is produced in vivo by reactions analogous to the in vitro ...

Mature crRNAs are key elements in CRISPR-Cas defense against genome invaders. These short RNAs are composed of unique repeat/spacer sequences that guide the Cas protein(s) to the cognate invading nucleic acids for their destruction. The biogenesis of mature crRNAs involves highly precise processing events.

In the biological sense, biogenesis is the spontaneous assembly of program-controlled, self-reproducing fluid automata under prebiotic conditions. In order to understand this phenomenon, principles of the theory of fluid automata should be laid down, as well as those of cycle stoichiometry which makes the exact, quantitative design of such chemically ...

FOLLOWING the demonstration that the amino-acid tryptophane can readily be converted by barley plants into the alkaloid gramine1, the study of the biogenesis of alkaloids carried on here has included investigations into the possibility that nicotine may arise from tryptophane in a manner similar to the formation of nicotinic acid in animals and ...

Peroxisome biogenesis conceptually consists of the (a) formation of the peroxisomal membrane, (b) import of proteins into the peroxisomal matrix and (c) proliferation of the organelles. Combined genetic and biochemical approaches led to the identification of 25 PEX genes-encoding proteins required for the biogenesis of peroxisomes, so-called peroxins ...

Cholesterol and Myelin Biogenesis
2010Myelin consists of several layers of tightly compacted membranes wrapped around axons in the nervous system. The main function of myelin is to provide electrical insulation around the axon to ensure the rapid propagation of nerve conduction. As the myelinating glia terminally differentiates, they begin to produce myelin membranes on a remarkable scale.
